This problem deals with the isothermal, steady-state expansion
of isobutane at, 35 [°C], from 1.5 [bar] to 5.0 [bar]. The
isobutane may be considered to behave as an ideal gas at the
initial pressure. However, at the final pressure, it is no longer
an ideal gas. The critical properties
(Tc and Pc) and
acentric factor (ω) of isobutane are, respectively:
408.1 [K], 3.648 [MPa],
and 0.181
